Long-term efficacy of slow-pathway catheter ablation in patients with documented but noninducible supraventricular tachycardia.

BACKGROUND: The long-term efficacy of radiofrequency catheter ablation of slow pathway in patients with dual atrioventricular node pathway and a documented but noninducible paroxysmal supraventricular tachycardia (PSVT) is not entirely clear. METHODS: Forty nine patients (Group A) with documented but noninducible PSVT and dual atrioventricular node pathway were prospectively studied. Programmed electrical stimulation induced a single atrioventricular node echo beat in 13 patients, and double echo beats in 9 at baseline or during isoproterenol infusion. Clinical and electrophysiological characteristics of Group A patients were compared with that of age- and gender-matched patients with dual atrioventricular node pathway but inducible PSVT (Group B). RESULTS: There was no significant difference in the electrophysiological properties of the fast and slow pathways between the two groups. Catheter ablation eliminated the slow pathway in all patients. There was no recurrence of PSVT in either Group A or Group B during the follow-up of 38 +/- 5 months. CONCLUSIONS: In patients with dual atrioventricular node pathway and a documented but noninducible PSVT, catheter ablation of slow pathway is highly effective in preventing tachycardia in long term.

Optical 3D surface digitizing in forensic medicine: 3D documentation of skin and bone injuries.

Photography process reduces a three-dimensional (3D) wound to a two-dimensional level. If there is a need for a high-resolution 3D dataset of an object, it needs to be three-dimensionally scanned. No-contact optical 3D digitizing surface scanners can be used as a powerful tool for wound and injury-causing instrument analysis in trauma cases. The 3D skin wound and a bone injury documentation using the optical scanner Advanced TOpometric Sensor (ATOS II, GOM International, Switzerland) will be demonstrated using two illustrative cases. Using this 3D optical digitizing method the wounds (the virtual 3D computer model of the skin and the bone injuries) and the virtual 3D model of the injury-causing tool are graphically documented in 3D in real-life size and shape and can be rotated in the CAD program on the computer screen. In addition, the virtual 3D models of the bone injuries and tool can now be compared in a 3D CAD program against one another in virtual space, to see if there are matching areas. Further steps in forensic medicine will be a full 3D surface documentation of the human body and all the forensic relevant injuries using optical 3D scanners.

Multimodal biometrics for identity documents (MBioID).

The MBioID initiative has been set up to address the following germane question: What and how biometric technologies could be deployed in identity documents in the foreseeable future? This research effort proposes to look at current and future practices and systems of establishing and using biometric identity documents (IDs) and evaluate their effectiveness in large-scale developments. The first objective of the MBioID project is to present a review document establishing the current state-of-the-art related to the use of multimodal biometrics in an IDs application. This research report gives the main definitions, properties and the framework of use related to biometrics, an overview of the main standards developed in the biometric industry and standardisation organisations to ensure interoperability, as well as some of the legal framework and the issues associated to biometrics such as privacy and personal data protection. The state-of-the-art in terms of technological development is also summarised for a range of single biometric modalities (2D and 3D face, fingerprint, iris, on-line signature and speech), chosen according to ICAO recommendations and availabilities, and for various multimodal approaches. This paper gives a summary of the main elements of that report. The second objective of the MBioID project is to propose relevant acquisition and evaluation protocols for a large-scale deployment of biometric IDs. Combined with the protocols, a multimodal database will be acquired in a realistic way, in order to be as close as possible to a real biometric IDs deployment. In this paper, the issues and solutions related to the acquisition setup are briefly presented.

Recent documents dating: an approach using radiocarbon techniques.

The possibility to develop an absolute technique, independent from the paper conservation conditions, to date recent paper documents (i.e. less than 50 years old) for forensics purposes is discussed. We suggest the possibility to use the curve representing the strong increase in the atmospheric radiocarbon concentration induced in the last 50 years by nuclear weapons tests as reference to date paper documents, with a resolution down to a few months. The results obtained in the analysis of two known age documents are presented together with a first order mathematical model developed in order to take into account the contributions of the different tree rings employed in the paper production.

Cross-institutional data exchange using the clinical document architecture (CDA).

PROBLEM: Although electronic communication of clinical data between various actors in the healthcare domain seems crucial for a cost-effective patient treatment, it is mostly restricted to paper based documents. In order to meet the growing need for improved data communication, it is necessary to overcome the barriers of software heterogeneity and lack of standards, especially in cross-institutional shared care communication. HL7's clinical document architecture (CDA) is a new and promising tool to exchange any clinical document. In this paper we show how CDA can be used to (1) share electronic discharge letters and other clinical data generated and stored in the hospitals electronic patient record (EPR) with general practitioners and (2) to transfer these clinical data to a personal electronic health record (EHR). The latter scenario is in routine use. Ease-of-use and data security and integrity were the main design principles in both scenarios. METHODS: Within the electronic patient record a data extraction and exporting mechanism has been built. For both scenarios appropriate data processing and transmission methods have been developed, and the receiving information systems have been prepared for the CDA based data input. RESULTS: Although there still remain technical and organizational issues to be solved, this is a promising method in order to enhance data exchange between hospital and primary care and to move towards an electronic patient record (EPR) and an electronic health record (EHR) crossing institutional borders. This paper describes the design and current implementation and discusses our experiences.

Health search engine with e-document analysis for reliable search results.

OBJECTIVE: After a review of the existing practical solution available to the citizen to retrieve eHealth document, the paper describes an original specialized search engine WRAPIN. METHOD: WRAPIN uses advanced cross lingual information retrieval technologies to check information quality by synthesizing medical concepts, conclusions and references contained in the health literature, to identify accurate, relevant sources. Thanks to MeSH terminology [1] (Medical Subject Headings from the U.S. National Library of Medicine) and advanced approaches such as conclusion extraction from structured document, reformulation of the query, WRAPIN offers to the user a privileged access to navigate through multilingual documents without language or medical prerequisites. RESULTS: The results of an evaluation conducted on the WRAPIN prototype show that results of the WRAPIN search engine are perceived as informative 65% (59% for a general-purpose search engine), reliable and trustworthy 72% (41% for the other engine) by users. But it leaves room for improvement such as the increase of database coverage, the explanation of the original functionalities and an audience adaptability. CONCLUSION: Thanks to evaluation outcomes, WRAPIN is now in exploitation on the HON web site (http://www.healthonnet.org), free of charge. Intended to the citizen it is a good alternative to general-purpose search engines when the user looks up trustworthy health and medical information or wants to check automatically a doubtful content of a Web page.

Marginal median SOM for document organization and retrieval.

The self-organizing map algorithm has been used successfully in document organization. We now propose using the same algorithm for document retrieval. Moreover, we test the performance of the self-organizing map by replacing the linear Least Mean Squares adaptation rule with the marginal median. We present two implementations of the latter variant of the self-organizing map by either quantifying the real valued feature vectors to integer valued ones or not. Experiments performed using both implementations demonstrate a superior performance against the self-organizing map based method in terms of the number of training iterations needed so that the mean square error (i.e. the average distortion) drops to the e(-1) = 36.788% of its initial value. Furthermore, the performance of a document organization and retrieval system employing the self-organizing map architecture and its variant is assessed using the average recall-precision curves evaluated on two corpora; the first comprises of manually selected web pages over the Internet having touristic content and the second one is the Reuters-21578, Distribution 1.0.

Unilateral retinal hemorrhages in documented cases of child abuse.

PURPOSE: To describe the occurrence of unilateral retinal hemorrhages in four cases of documented child abuse, including a case in which retinal hemorrhages were an incidental finding on routine examination. METHODS: Case reports. RESULTS: Three children, 5 to 17 months of age, with suspected child abuse had fundus examinations with a dilated pupil as part of their evaluation. An additional child, 6 months of age, received fundus examination with a dilated pupil as part of follow-up for regressed retinopathy of prematurity. Each of the four children had extensive retinal or preretinal hemorrhages in one eye only. Three of the four had ecchymoses on the ipsilateral face or neck. Two had evidence of bone fractures on skeletal surveys. All four had neuroimaging that documented cerebral hemorrhage or infarct. In all four cases an adult caretaker was found responsible for shaking, choking, or squeezing the child. One child died. Two had resolution of retinal hemorrhage, whereas one required vitrectomy. All three had at least partial recovery of vision in the affected eye after amblyopia treatment. CONCLUSION: In cases of documented child abuse, unilateral retinal or preretinal hemorrhages may be present. Ophthalmologists should recognize that unilateral retinal or preretinal hemorrhages may be associated with child abuse.

Still photography versus videotaping for documentation of cecal intubation: a prospective study.

BACKGROUND: Documentation of cecal intubation is important for credentialing and continuous quality improvement. However, convincing cecal photographs can be difficult to obtain. The aims of the study were to determine (1) the anatomic variations and photographic factors associated with convincing cecal photographs; (2) whether a prospective attempt to capture specific features resulted in more convincing photographs; and (3) how a prospective attempt at capturing convincing cecal features during still photography compares with videotaping as a method of documenting cecal intubation. METHODS: A single examiner evaluating 165 consecutive patients photographed the entire cecum from just distal to the ileocecal valve, the appendiceal orifice, the ileocecal valve orifice, and in the last 110 consecutive cases, the terminal ileum, if it could be intubated. The photographs were then scored by 8 experts according to how convinced they were that cecal intubation had occurred. Features associated with high and low scores were determined, and 50 additional consecutive patients were photographed with a specific effort to capture these features, along with videotaping of the cecum. These photographs and videotapes were then scored by 7 of the 8 experts on a scale of 1 to 5, with 5 representing "definitely the cecum." RESULTS: There was marked variation in scores of still photographs among reviewers. A combination of photographs produced the highest mean score and the highest percentage of scores that were either "probably" or "definitely" of the cecum. The photograph of the cecum from just distal to the ileocecal valve was most convincing and the terminal ileum photograph was least convincing. In the 50 cases in which an attempt was made to capture specific features, mean scores improved for the overall cecal photograph by 0.10, the appendiceal orifice by 0.23, the ileocecal valve lips by 0.20, and the terminal ileum by 0. 19. The cecum, appendiceal orifice, valve lips, and terminal ileum photographs for the last 50 patients were scored higher than those from the first 165 patients by 4, 4, 4, and 5 reviewers, respectively. Videotapes were consistently convincing (overall mean score 4.78 out of 5) and were scored more convincing than the combination of still photos from the final 50 cases by 6 of 7 reviewers. CONCLUSIONS: Still photography of the cecum can be improved somewhat by attempting to capture specific cecal features. However, because of anatomic variation among normal individuals, still photography remains inconsistently convincing. A combination of photographs is most convincing. Videotaping of the cecum is consistently convincing and would appear to serve effectively as a means of documenting cecal intubation rates for the purposes of continuous quality improvement and credentialing.

Forensic documentation of battered pregnant women.

Patients hurt during intimate partner abuse are crime victims who may seek legal relief and protection from one or more court systems. What the health care provider documents or does not document may have tremendous forensic implications; yet, most health care providers have received little formal training in clinical forensics. Being subpoenaed to court as a witness can trigger fear and anxiety. This article reviews the basic principles of clinical forensic documentation, evidence collection and preservation, forensic photography, and accurate wound identification, as well as tips on working with police and on testifying in court.

The validity and reliability of photographic documentation of proliferative vitreoretinopathy.

The Silicone Study is a multicentered, randomized surgical trial designed to compare the tamponade effectiveness of silicone oil versus long-acting gas in the treatment of proliferative vitreoretinopathy (PVR) by vitrectomy and associated techniques. Fundus photographs are taken to provide documentation of the anatomic status of eyes proposed for entry and are graded at an independent Reading Center. This article describes the protocol for photographic documentation of PVR as a continuum of increasing pathology, in which the pathology may only be present in the anterior retina, and the retina is usually highly elevated. In a validity and reliability study, agreement between photographic and clinical observation within one step was obtained for 88% of the eyes; intra- and inter-observer agreement within one step was 85 and 80%, respectively. Differences between the surgeon's grade and the Reading Center's were caused about equally by disagreement regarding extent of fixed folds and width of the funnel. Rarely did peripheral folds not visible in the photographs appear to be the sole explanation of the disagreement. Differences among readers were concerned mainly with differentiation of true full-thickness fixed folds from folds due to simple redundancy of the detached retina. These results demonstrate that complicated retinal detachment (RD) can be photographically documented and independently assessed.

[Evaluation of the quality of communication between levels of care through the inter-consultation document].

OBJECTIVES: To evaluate the quality and improvement of compliance in the inter-consultation documents of the primary care team (PCT). DESIGN: Entire care cycle. SETTING: Primary care (PC). MEASUREMENTS: Dimension studied: scientific-technical quality. SUBJECTS: all the inter-consultation documents (ID-1) sent by PC doctors from Irun Health Centre to specialist clinics over a 15-day period. 223 ID-1 for evaluation in April 1998, and 287 for re-evaluation in October 1998. Type of evaluation: retrospective. SOURCE OF DATA: inter-consultation documents and clinical records. CRITERIA: explicit and standard. Corrective measures: educational (discussion of results in meeting of the PCT). RESULTS: A statistically significant improvement was found at the re-evaluation: basic personal details (91.5%-96.8%), legibility (86%-92.7%), medical history and/or customary medication (35.9%-50%) and symptoms (77.8%-87.2%). Good quality levels rose from 20.6% to 42.5%; and bad quality levels fell from 40.8% to 33.4%. 22.2% of our referrals received a reply. 34% of the lack of replies was because of no report from the specialist, 47.8% were attributed to the patient or circuit, and 18% of the patients were awaiting test results. CONCLUSIONS: The information supplied in the ID-1 improved significantly after the quality cycle. Knowing our habitual working practice can serve to stimulate improvement. The criteria we complied with least were: reference to personal antecedents and/or habitual medication, physical examination, and therapeutic measures employed. There was a huge loss of information in the replies to our referrals.

Meanings in policy: a textual analysis of Canada's "Achieving Health For All" document.

This paper presents a textual analysis of a key Canadian health policy document--Achieving Health for All (AHFA). It begins by establishing the importance of policy language and an interpretive approach to reveal dominant meanings and assumptions. This approach points out the significance of language and its contexts (text and intertext) and of developing a formal analytic strategy, based on semiotics. The paper concludes with a detailed, illustrated analysis of AHFA, suggesting that the document's discourse, through appealing to all, with emphases on the nation, community and all Canadians, establishes a frame of individual responsibility and rights, health promotion and broad health determinants--a frame that resonates with the cost-constrained nature of health care delivery-as found in provincial reform documents in the 1980s and 1990s.

Erectile dysfunction prevalence, time of onset and association with risk factors in 300 consecutive patients with acute chest pain and angiographically documented coronary artery disease.

OBJECTIVES: The aim of this study was to assess erectile dysfunction prevalence, time of onset and association with risk factors in patients with acute chest pain and angiographically documented coronary artery disease. METHODS: 300 consecutive patients with acute chest pain and angiographically documented coronary artery disease were assessed using a semi-structured interview investigating their medical and sexual histories, the International Index of Erectile Function and other instruments. RESULTS: Patient mean age was 62.5+/-8 years (range 33-86 years). Mean duration of symptoms or signs of myocardial ischaemia prior to enrollment in the study was 49 months (range 1-200). Coronary angiography showed 1-, 2- and 3-vessel disease in 98 (32.6%), 88 (29.3%) and 114 (38%) patients, respectively. The prevalence of ED among all patients was 49% (147/300). Erectile dysfunction was scored as mild, mild to moderate, moderate and severe in 21 (14%), 31 (21%), 20 (14%), and 75 (51%) of patients, respectively. There was no significant difference between patients with ED (n=147) or without ED (n=153) as far as clinical and angiographic characteristics were concerned. In the 147 patients with co-existing ED and CAD, ED symptoms were reported as having become clinically evident prior to CAD symptoms by 99/147 (67%) patients. The mean time interval between the onset of ED and CAD was 38.8 months (range 1-168). There was no significant difference in terms of risk factor distribution and clinical and angiographic characteristics between patients with the onset of ED before vs. after CAD diagnosis. Interestingly, all patients with type I diabetes and ED actually developed sexual dysfunction before CAD onset (p<0.001). CONCLUSIONS: Our study suggests that a significant proportion of patients with angiographically documented coronary artery disease have erectile dysfunction and that this latter condition may become evident prior to angina symptoms in almost 70% of cases. Future studies including a control group of patients with coronary artery disease and normal erectile function are required in order to verify whether erectile dysfunction may be considered a real predictor of ischemic heart disease.

The dynamic development of the muzzle imprint by contact gunshot: high-speed documentation utilizing the "skin-skull-brain model".

Many contact gunshots produce a muzzle imprint in the skin of the victim. Different mechanisms have been discussed in literature as being responsible for the creation of the muzzle imprint. Experimenting upon the synthetic non biological skin-skull-brain model, our goal was to document and study the creation of the muzzle imprint with the aid of high-speed photography. In our experiments, we could document with our high-speed photography (at exposure rates in the range of nanoseconds) the bulging, the pressing against the muzzle, and the splitting of the artificial skin. Furthermore, it was possible to photographically record the back pattern of synthetic tissue particles. And, the soot and gunpowder cavity could be reproduced experimentally. In conclusion the experiments completed with the skin-skull-brain model, using high-speed photography for documentation, show the promising possibilities of experimental ballistics with body models.
